Abstract

The Micro-electromechanical Hybrid Gyroscope adopts the principle of traditional Dynamically Tuned Gyroscope and uses micro-machining technology to realize Gyroscopes of small size and mass with comparable performance. The rotor subassembly of the hybrid Gyroscope needs to be driven by an electrical motor at a higher speed to impart the required angular moment. The miniature motor has to operate the rotor subassembly of the Gyroscope at a steady speed irrespective of the bearing friction fluctuations and other external disturbances. This paper presents the design and realization details of a four pole slot-less, easy-to-assemble, radial flux BLDC motor designed for a Micro-electromechanical Hybrid Gyroscope.
混合陀螺仪微型电机的设计
微机电混合陀螺仪采用传统的动态调谐陀螺仪的工作原理,利用微加工技术实现小尺寸、小质量、性能相当的陀螺仪。混合陀螺仪的转子组件需要由电动机以更高的速度驱动,以提供所需的角矩。微型电机必须以稳定的速度运行陀螺仪转子组件,而不受轴承摩擦波动和其他外部干扰的影响。介绍了一种用于微机混合陀螺仪的四极无槽、易组装径向磁通无刷直流电机的设计与实现。
